Constructor Detail

PolygonIterator

public PolygonIterator(Polygon2D pl,
                       java.awt.geom.AffineTransform at)

Create a new iterator over the given polygon and with the given transform. If the transform is null, that is taken to be the same as a unit Transform.

Method Detail

currentSegment

public int currentSegment(double[] coords)

Get the current segment

Specified by:

getWindingRule

public int getWindingRule()

Return the winding rule. This is WIND_NON_ZERO.

Specified by:

getWindingRule in interface java.awt.geom.PathIterator

isDone

public boolean isDone()
